Definitions

  • the attenuation unit 402 performs an attenuation process to reduce the amplitude, and the first pulse transformer 403 and the patient circuit 4 a are secondary. While maintaining insulation from the circuit 4b, the attenuated imaging signal is transmitted from the patient circuit 4a side to the secondary circuit 4b side.
  • the waveform quality such as the S / N ratio
  • the signal amplitude proportional to the radiation noise is lowered to suppress the radiation noise, and the insulation is maintained while maintaining the waveform quality such as the S / N ratio. Signal transmission between circuits can be performed.
  • the imaging signal receiving unit 404 a is provided on the secondary circuit 4 b side, receives the imaging signal restored by the amplification unit 405 a, and transmits the received imaging signal to the second signal processing unit 43.
  • the imaging signal transmission unit 401a converts the signal into a differential signal.
  • the signal transmitted by the first pulse transformer 403a may be a differential signal, and the attenuation unit. It may be converted into a differential signal in 402a.
  • FIG. 6 is a block diagram illustrating a schematic configuration of the insulating transmission unit of the endoscope system according to the fourth embodiment.

Abstract

La présente invention concerne un appareil médical qui effectue une transmission de signal entre deux circuits électriquement isolés l'un de l'autre, un circuit ayant un premier potentiel de référence et l'autre circuit ayant un deuxième potentiel de référence qui est différent du premier potentiel de référence. L'appareil médical comprend : une unité d'atténuation qui est disposée sur le côté du premier circuit et atténue l'amplitude d'un signal reçu ; et un transformateur d'impulsions qui transmet le signal atténué par l'unité d'atténuation du premier circuit à l'autre circuit tout en maintenant le premier circuit et l'autre circuit isolés l'un de l'autre.
